Why not?  In your input source class's "doGetNextFrame()", just do 
something like
         fFrameSize = PES_packet_size - PES_header_size;
         memmove(fTo, &dataPtr[PES_header_size], fFrameSize);
instead of
         fFrameSize = PES_packet_size;
         memmove(fTo, dataPtr, fFrameSize);

Well, you could use "MPEG2TransportStreamFromPESSource", which generates a 
Transport Stream.  (See the code for the "testMPEG2TransportStreamer" demo 
application.)
